There are 111 people in the canteen of the contracting site, and one person is in 21 yuan every day. In about two years, the water, electricity and fuel, including prefabricated houses, are paid by themselves for about 1.5-1.2 million.

three meals for 21,111 people is 2,111 yuan a day. Your food is a little decent, and the cost will not be lower than 1,211. If it is lower than 1,211, the food will basically be invisible. It is estimated that few people are willing to eat it. Then your income is 811 every day.

Then look at your other expenses. Your manpower is 1 cooks and 4 handymen. The master is 3,511 yuan (this is really extremely low. Anyway, there are less than 4,511 people here, so it's not too much trouble to reduce it by 1,111 yuan), and the handymen is 1,511 yuan, * * * is 6,111 yuan, and your manpower is 9,511 yuan/. Board houses cost RMB 111,111/year, which is RMB 274/day. In this way, the expenditure for one day is 591 yuan. You can earn 211 a day. You can earn 146111 yuan in two years and 71111 yuan in one year.

This is the best situation. In fact, there will be many messy accidents, and the manual calculation is low. In addition, your initial investment, gifts, and whether the workers will come to eat or not, does it count as money or something? It is not meaningful to have 41,111 to 51,111 a year.
